Events

The Roman denarius coin is minted for the first time.
The Romans found a colony at Malventum which they, for superstitious reasons, call Beneventum (since male means bad and bene means good in Latin).

Chremonides, an Athenian statesman and general, issues the Decree of Chremonides, creating an alliance between Sparta, Athens, and Ptolemy II of Egypt. The origins of this alliance lay in the continuing desire of many Greek states, notably Athens and Sparta, for a restoration of their former independence, along with the desire of Ptolemy II to create troubles for his rival Antigonus II, King of Macedonia. Ptolemy II's ambitions in the Aegean Sea are threatened by Antigonus Gonatas' fleet, so he carefully builds up a coalition against Macedonia in Greece. He especially cultivates Athens by supplying the city with grain.
